Exfoliation is one of the key components in having young radiant skin. Exfoliation removes dead skin cells while rejuvenating new skin cells. If done properly, exfoliation leaves the skin smooth, vibrate, and fresh while diminishing wrinkles, fine lines, and crows feet. You should exfoliate one to three times a week. Don't over due it or scrub too hard. Harsh chemical exfoliants used in salons can cause cell damage.
